Patented Aug. 25, 1931 (UNITED STATES PATENT OFFICE JOHN THOMASBILDERBECK, OF LOS ANGELES, CALIFORNIA, ASSIGNOB '10 WESTERN CONCRETEPIPE COMPANY, OF LOS ANGELB, CALIFORNIA PUMP Application filed January30, 1929. Serial No. 836,108.

This invention relates to devices designed to actuate a number ofpumping plungers by means of a rotating head.

One of the objects of this invention is to design the rotating head witha slantin face in axial direction to contact with an slidingly ride overa number of pumping plungers, the pumping plungers being yieldinglymounted by means of springs against the tension of which the plungersare pressed by the rotating head so that the plungers automatically movein one direct-ion against the head by means of the springs.

Another object is to provide a sectional head of which one section canbe adjusted with respect to its actuating front face in relation to theother section.

Another object is to provide a pivotal inter-connection between thesections of the actuating head.

Another object is to provide adjusting means by which the valves andplungers can be controlled from zero to 100% pumping and actingmovements.

Another object is to provide a pump of this type in which the actuatinghead and the plungers are incased in a lubricant holding chamber.

Another object is to provide communications between the lubricantchamber and the working side of the plungers whereby the lubricant inthe pump chamber can be used for producing a desired pressure on thedischarging end of the pump.

Another object is to provide a pump operating under constant speed anddesigned to deliver a variable volume. Other objects will appear fromthe following description and appended claims as well as from theaccompanying drawings, in which Fig. 1 is a general longitudinalmidsectional view of a simple pump structure with a revolving actuatingshaft and an also revolving actuating head provided with an axiallyinclined adjustable contact means between the actuating head and aplurality of axially movable valves yieldingly contacting with the headfor continuous pumping move ments and the several parts incased in alubricant holding chamber according to this invention.

Fig. 2 is a top plan view of the actuating head seen in the direction ofthe arrow 2 in Fig. 1.

Fi 3 is a cross section through the adjusta le head on line 3-3 of Fi 2.

.Fig. 4 is a fragmentary top p an view of the base blockin small scaleroughly outlining a plurality of plunger holes arranged in a circle andother holes by which this base block is connected with other parts ofthe pump.

As illustrated a base blocki5 is provided with an upwardly projectingcentral pin 6. This block is also provided with a plurality of plungerholes 7 and bolt holes 8.

A plunger 9 is mounted in relation to each plunger hole 7. The plungeris provided with an enlarged head 10 facilitating an insertion of aspring 11 between the head 10 and the block 5 whereby the plunger isautomatically lifted for suction operations.

Thespring actuated plungers are disposed to contact with an adjustablecross'head. The cross head consists principally of two pivotallyconnected members 12 and 13, the pivot being indicated at 14.

A special ball bearing consisting of the plates 15 and 16 with balls 17inserted between the plates 15 and 16 is disposed between the cross headand the top of the plungers, to reduce the friction between the crosshead and the plungers. The cross head is turnably mounted with itshollow shaft end 18 in the top block 19 and is geared or operativelyconnected to the crosswise extendin driving shaft 20, a ball bearing 21being Inserted between the cross head and the top block 19 to reduce thefriction between the cross head and the top block 19.

Adjustability is accomplished between the members 13 and 12 of the crosshead by a spindle 22 disposed through the hollow of the shaft 18 andthrough the central hollow of the upper member 12 so that the lower end23 of the spindle contacts with the lower member 13 of the cross head.

The spindle is sectioned to allow an insertion of the ball 24 wherebythe friction betion, or, in ot er wor s, to a POSItiOII squarelycrosswise to the axis of the whole structure and the axes of theplungers.

This ad'usting of the cross head and especially of t e lower member 13including the plates 15 and 16 is accomplished by a turnmg of thespindle 22 so that the plungers may be controlled from an extreme longstroke to absolutely inoperative position.

In Fig. 1, for instance, the plunger head 10, in the left hand side ofthe drawings, is shown in its topmost or extreme outermost positionwhile in dotted lines indicated at 10. the lowermost position of thesame plunger head is indicated. .The movements of the several lungersare utilized to actuate or control t e check valves 27 and 28.

An outward movement of the plunger 9 results in an opening of the valve27 and in a drawing of a medium into the compartment 29.

A downward stroke of the plunger results in an automatic closing of'thevalve 27 and man opening of the valve 28 whereby a medium is dischargedin the direction of the arrows 30.

All the several parts disposed between the base block 5 and the topblock 19 are incased as indicated at 31 so that a lubricant can bemaintained within this casing around all the several working parts. Thislubricant can also be used as a pumping medium to be drawn through theopenings 32 in the direction of the arrows 33 past the valves 27 intothe compartment 29.

An inlet connection 34 is providedon the casing 31 whereby a lubricantor similar pumping medium can be sup lied in a required amount tomaintain su cient of this medium within the casing to facilitate theproper operation of this pump.

The connection 34, of course, can be used to serve as a suctionconnection for this pump to draw any material that may be drawn by anypump, and the discharging connection 35, of course, may be used fordischarging any material in any customary manner. However, this pump isespecially suited for producinga high pressure on a variable capacity offrom zero to 100%;

Since'the pump 0 crates continuously and since a plurality o valves orplungers can be installed, depending only on the size of the pump andthe size of the plungers, it must be understood that this pump can bemade as a non-pulsating apparatus.

It, furthermore, mustbe understood that 'at a constant speed the volumeto pass through the pump can be varied at the will of the operator.

Having thus described my invention, I
